[PATCH] mmc: cavium: Improve request handling by proper use of API

From: Wojciech Bartczak
Date: Mon Nov 15 2021 - 19:09:45 EST


The driver for cavium/marvell platforms uses directly mrq->done() callback
to signalize the request completion. This method to finalize request
processing is not correct.

Following fix introduces proper use of mmc_request_done() API for
all paths involved into handling MMC core requests.
